VHDL-200x-dta Charter

• Enhance VHDL data types abstractions.

• Serve as a resource to other groups contemplating changes to the existing VHDL data types and abstraction mechanisms.

VHDL-200x-dta Responsibilities

• Collect suggestions for change

• Analyze suggestions for change

• Analyze proposals and language designs from other subgroups

• Develop language designs for changes and proposals

• Recommend changes to language in dta

VHDL-200x-dta Requests

• Object Oriented Features• Variant Records (“free unions”)• New standard data types

– Boolean, integer, real vectors

• Associative arrays• Sparse arrays• Enhanced object initialization• Built-in lists

VHDL-200x-dta Status

• We wish to leverage off of previous work (e.g., in OO and variant records)

• We are actively looking for proposals

• We are actively looking for champions for proposals
